Sinusoidal PWM control
Adjustable within the range of 50 to 660V by correcting the supply voltage (not adjustable above the input
voltage)
0.5 to 200.0Hz, default setting: 0.5 to 80Hz, maximum frequency: 30 to 200Hz
0.1Hz: analog input (when the max. frequency is 100Hz), 0.01Hz: Operation panel setting and
communication setting.
Digital setting: within ±0.01% of the max. frequency (-10 to +60°C)
Analog setting: within ±0.5% of the max. frequency (25°C ±10°C)
V/F constant, variable torque, automatic torque boost, vector control, automatic energy-saving, PM motor
control. Auto-tuning. Base frequency (25 - 200Hz) adjusting to 1 or 2, torque boost (0 - 30%) adjusting to
1 or 2, adjusting frequency at start (0.5 - 10Hz)
External frequency potentiometer (connectable to a potentiometer with a rated impedance of 1 - 10k
- 10Vdc (input impedance: VIA/VIB=30k
The characteristic can be set arbitrarily by two-point setting. Possible to set individually for three
functions: analog input (VIA and VIB) and communication command.
Three frequencies can be set. Setting of the jump frequency and the range.
Upper-limit frequency: 0 to max. frequency, lower-limit frequency: 0 to upper-limit frequency
Adjustable within a range of 6.0 to 16.0Hz (default: 8 or 12kHz).
Setting of proportional gain, integral gain, differential gain and control wait time. Checking whether the
amount of processing amount and the amount of feedback agree.
Selectable from among acceleration/deceleration times 1 and 2 (0.0 to 3200 sec.). Automatic
acceleration/deceleration function. S-pattern acceleration/deceleration 1 and 2 and S-pattern adjustable.
Control of forced rapid deceleration and dynamic rapid deceleration
Braking start-up frequency: 0 to maximum frequency, braking rate: 0 to 100%, braking time: 0 to 20
seconds, emergency DC braking
Possible to select from among 57 functions, such as forward/reverse run signal input, operation base
signal input and reset signal input, to assign to 4 input terminals. Logic selectable between sink and
source.
Possible to select from among 58 functions, such as upper/lower limit frequency signal output, low speed
detection signal output, specified speed reach signal output and failure signal output, to assign to FL
relay output, RY output terminals.
The RUN and STOP keys on the operation panel are used to start and stop operation, respectively. The
switching between forward run and reverse run can be done from one of the three control units: operation
panel, terminal board and external control unit.
Base frequency + 7-speed operation possible by changing the combination of 3 contacts on the terminal
board.
Capable of restarting automatically after a check of the main circuit elements in case the protective
function is activated. 10 times (Max.) (selectable with a parameter)
Possible to write-protect parameters and to prohibit the change of panel frequency settings and the use
of operation panel for operation, emergency stop or resetting.
In the event of a momentary power failure, the inverter reads the rotational speed of the coasting motor
and outputs a frequency appropriate to the rotational speed in order to restart the motor smoothly. This
function can also be used when switching to commercial power.
The motor is allowed to "slip" according to the load torque current.
1c-contact output: (250Vac-0.5A-cosФ=0.4)
